Chapter 242: A Comet Falls from the Sky
In the solar system, because the violent solar wind when the sun was first formed drove the water to the outer reaches of the galaxy, the water is now mainly in the form of ice in the rings of Saturn, Jupiter's moon Europa, Neptune, Uranus and comets!

Undoubtedly, compared with those planets and satellites, those comets are the most suitable for the current situation.

You must know that there are billions of comets traveling back and forth in the entire solar system!

To be precise, a comet is a small celestial body in the universe. It is composed of a comet nucleus, a coma hair, and a comet tail. When it moves toward the sun, due to the existence of the solar wind, the material of the comet nucleus sublimates, thus forming the comet hair and comet tail. .

Therefore, its mass is mainly concentrated on the comet nucleus, which is usually composed of stones, iron, dust, ammonia, methane, ice, etc., and most comets have a larger proportion of ice.

Comet nuclei vary in size. Some comets have a core diameter of 200 meters, while others have a diameter of [-] to [-] kilometers!
There is even a scientific point of view that the reason why the blue star, unlike Mars and Venus, has a large amount of water resources is that a large number of comet impacts brought water at the beginning of its formation.

Actually it's easy to understand.

The flesh god travels between Blue Star and Mars for 60 hours, which is only [-] tons of water.

And if a comet nucleus with a diameter of 50 meters can be captured, then at least [-] to [-] tons of water will be obtained!

If a comet nucleus with a diameter of one kilometer can be captured, it will be 500 million tons of water!

It is enough for the physical body to go back and forth between Blue Star and Mars eight times. How much time will this save?
Three hours later, the flesh god returned from Blue Star, and after unloading the materials at the Mars base, he brought 30 tons of seawater to Jianmu, barely quenching Jianmu's thirst.

Afterwards, all the Yuan energy detectors around the body god were turned on, and circles of invisible Yuan energy fluctuations spread out towards the surroundings.

Now the detection of the physical god's primordial energy can reach a radius of 5000 million kilometers, and it's just a 360-degree scan length centered on it.

But now the physical god has chosen a direction to scan at a [-]-degree angle, then the scanning length will be extended ten times, reaching a terrifying level of [-] million kilometers!
What kind of concept is [-] million kilometers?
More than three times the distance from the blue star to the sun.

Almost all of them can be scanned directly from Mars to Jupiter, and the distance from Mars to the sun is only more than 2 million kilometers.

It only takes half a minute for the flesh god to scan all the space within this range.

The number of comets operating in this range exceeds [-].

Of course, the comets that are far away are directly eliminated by Wang Dashu, and the remaining 200 comets are all within a radius of 1000 million kilometers from the flesh god, which means that it only takes six hours for the flesh god to go back and forth.

The remaining more than 200 comets continued to be eliminated by Wang Dashu, and finally he selected a comet with a nucleus diameter of about 260 meters.

This comet is flying towards the outer solar system at a distance of 60 kilometers from Mars.

The distance is undoubtedly one of the main reasons why Wang Dashu chose this comet.

And in the core of the comet, ice occupies 80.00%, from which it can be calculated that the comet has more than 700 million tons of water!
Compared with the 60 tons of seawater brought back by the flesh god in [-] hours, once this comet is brought back to Mars, it will not only allow Jianmu to obtain a lot of water, but also allow Mars to solve part of the current situation of water shortage .

The huge physical god flew towards the comet at high speed, and the radar station of the Mars base faithfully discovered this scene.

To the surprise of those radar operators, the flesh god did not fly towards the blue star as usual, but rushed towards a comet that skimmed the orbit of Mars.

What's happening here?
No one knows what's going on.

This unknown comet is flying at a speed of 56 kilometers per second, which is very slow compared to the speed of the flesh-body god.

After more than ten minutes, the flesh god approached this unknown comet and fired a nano-drawn wire towards it.

As dozens of blue lights fell on the comet, the huge body of the flesh god was also dragged along.

This is not surprising. Compared with comets, the overall mass of the flesh god is much smaller.

But as the flesh-body god turned around and changed the direction of flight, the tens of nanowires tensed up in the space, but in an instant, all the nanowires collapsed under the action of huge force!

For the flesh god, this is also a helpless thing.

Although the nano-drawing wire is extremely tough, it still cannot bear the impact of tens of millions of tons brought by the comet.

But in this way, the speed of the comet suddenly slowed down a little.

Nano drag wires are much cheaper than self-guided missiles for physical gods.

The nanofilament generator is filled with a special liquid that is ejected at extremely high speed to form nanofilaments.

Therefore, after it broke, the flesh god immediately spewed out nanofilaments, sticking the comet tightly, without giving it the slightest chance to escape.

Under the continuous traction, the comet soon stopped its rushing force, and was dragged by the flesh god towards Mars instead.

In the past, the total time spent before and after capturing the comet was only more than 20 minutes, but it took one and a half hours to return to Mars.

No way, even Wang Dashu didn't dare to let the comet hit Mars at high speed.

Although being hit by a comet with a diameter of more than 200 meters in the volume of Mars will not affect the overall stability of Mars, it will undoubtedly be a great disaster for humans on Mars.

The earthquake caused during this period is enough to completely destroy the Mars base.

Therefore, the speed at which the flesh-body god pulled the comet at the beginning was only [-] kilometers per second at the highest speed, and when it was close to Mars, it slowed down to every [-] kilometers. kilometers into the Martian atmosphere.

I have to say, this scene is very spectacular.

Although the atmosphere of Mars is very thin, when the comet fell at a height of six kilometers per second, it still rubbed out a dazzling flame, like a huge meteor falling towards a certain place on Mars.

boom!
The moment the comet hit the surface of Mars, a huge amount of Martian dust was stirred up, and the Martian dust shot up into the sky, forming a huge mushroom cloud in a few breaths, like a nuclear bomb exploding on the surface of Mars.

The huge shock wave spread out in a circle, and where it passed, the gravel splashed like a heavy artillery bombardment.

But the most frightening thing was the seismic fluctuations caused by it. In an instant, even the Mars base thousands of kilometers away began to rise and fall with the surface, and the Martian immigrants were so shocked that they lay on the ground and dared not move.
